2 Claims.

The present invention relates to bobbin supports and, more particularly, to an arrangement of bobbin supports on the creels of spinning machines and the like.

The arrangement of the supports or holders for the bobbins on the creel of a spinning machine is of vital importance with regard to the output and the length of the respective spinning machine and also with respect to the speed at which the unloaded bobbins can be removed from the supports or ho1ders and be replaced by new loaded bobbins.

It is, therefore, an object of this invention to arrange the bobbin supports or holders on the creel of a spinning machine or the like in such a manner thatevery bobbin which may be supported thereby can easily be reached and exchanged in the shortest possible time without interfering with the unloading of the other bobbins.

It is also an object of this invention to provide a bobbin support arrangement on the creels of spinning machines or the like, which will make it possible to arrange considerably more bobbins on a given creel area than it was possible heretofore with the same type of bobbins.

It is still another object of this invention to arrange the bobbin holders or supports on the creels of spinning machines or the like in such a manner that the bobbins can easily be watched by the operator from practically any position at arrangement according to the invention.

General arrangement According to the present invention, the bobbin supports or bobbin holders connected to the creel of a spinning machine are of different length so that the lower ends of two adjacent bobbin holders are arranged at different horizontal planes spaced from each other by a considerable portion of the length of a bobbin to be supported by a bobbin holder. Preferably, the distance between the said two horizontal planes is such that when two adjacent bobbin holders carry bobbins fully loaded with the normal quantity of sliver, the largest diameter of the wound up sliver on the lower bobbin will be lower than the largest diameter of the sliver on the upper bobbin. Thus, by arranging the bobbin holders in pairs, each pair consisting of one short and one adjacent long bobbin holder, the bobbin holders of each pair can be brought very close together, even to such an extent that the longitudinal cylindrical extension of the fiber material wound up on the bobbin of one bobbin holder will overlap with the longitudinal cylindrical extension of the fiber material wound up on the bobbin of the adjacent bobbin holder, provided, of course, that the lower ends of the two adjacent bobbin holders are located in two horizontal planes which are correspondingly spaced from each other. In other words, if desired, the fiber material on one bobbin may partially be below the fiber material on the adjacent bobbin.

The arrangement may be such that the bobbin holders of each pair are arranged in a row eX- tending in the longitudinal direction of the creel.

From the above it will be evident that the present invention makes it possible to arranged a pre: determined number of bobbin holders and therefore of bobbins on a materially smaller creel area than was heretofore possible with a conventional bobbin holder arrangement. The new arrangement according to the invention also makes the bobbins far better accessible and enables the operator better to watch a greater number of bobbins.

Structural arrangement Referring now to the drawing in detail and Fig. 1 thereof in particular, this figure shows how, according to the principle of the invention, a long bobbin holder I is arranged near a short bobbin holder 2. The bobbin holders I and 2 are in any convenient manner, e. g. by means of a threaded section 3 and nut 4, connected to and suspended on the creel 5.

The receiving andholding mechanism of the bobbin holders I and 2, which difier from each other merely in the length of the shafts 6 and 7, may be of any standard character and does not form apart of the present invention. Preferably, bobbin holders are used of the type which incorporate an anti-friction bearing for supporting the bobbin 8 pendulously from underneath the creel board. Reference numeral 9 designates the fiber material or sliver wound up on the sleeve I I which latter is carried by the bobbin 8 in the conventional manner.

As stated above, according to the present invention, the short and long bobbin holders are arranged in pairs, i. e. a long bobbin holder is arranged adjacent a short bobbin holder. This arrangement may be such that the bobbin holders of a pair are arranged in a. line extending in the longitudinal direction of the creel board.

As will be clear from the arrangement of Fig. 1, the vertical distance between the horizontal plane tangential to the lower end of .the short bobbin holder and the horizontal plane tangential to the lower end of the long bobbin holder is greater than half the length of the bobbin 8. Preferably, the said distance is selected so that it nearly equals the length of a bobbin. In this Way, the shaft 7 of the long bobbin holder i can be arranged so close to the shaft 6 of the short bobbin holder 2 that the space between the sliver loaded bobbin on the short bobbin holder 2 and the adjacent shaft 7 is just sufficient to allow the introduction of the operators hand therebetween to load and unload the short bobbin holder 2. Obviously, the loading and unloading of the long bobbin holder 1 is no problem at all since the bobbin carried thereby, is always materially lower than the adjacent bobbins carried by the respective short bobbin holders,

A practical arrangement according to the present invention is shown in Fig. 2 according to which the pairs of short and long bobbin holders are aligned in the longitudinal direction of the creel board 5. In other words, in one and the same longitudinal row, a short bobbin holder 2 alternates with a long bobbin 'holder I. This figure also shows how easily the loaded bobbins can be viewed and handled.

Referring nowto Fig. 3, the arrangement illustrated therein shows in perspective two longitudinal rows of bobbin holders, each row containing short and long bobbin holders arranged in conformity with Fig. 2. However, the rear bobbin holders are offset with regard to the respective bobbin holders in front thereof by a distance d which distance may be selected according to the particular circumstances involved, 1. e. design of the machine, length of the machine, positions of the working stations of the machine, the width of the drawing frames, etc. The rear bobbin holders are shown in Fig. 3 as being offset toward the left, but, if desired, they may be offset toward the right.

7 The arrangement of Fig. 3 makes it possible to assemble a particularly great number of bobbins underneath a relatively small area of a creel board while still having each bobbin easily accessible and visible.

It is, of course, understood that the arrangements shown in the drawing may without difficulties be duplicated toward the other side of the creel board. It is further to be understood that the present invention is, by no means, limited to the particular arrangements shown in the drawing but also comprises any modifications Within the scope of the appended claims.

What I'claim is:

.1. A bobbin holder arrangement for spinning and preparing machines which comprises in combination, a creel board, a first row of alternately short and long bobbin holders substantially vertioally suspended from said creel board and adapted detachably to support the same type of bobbins, and a second row of alternately short and long bobbin holders substantially identical to said short and long bobbin holders of said first row and substantially vertically suspended from said creel board, both said first row and said second row extending in the longitudinal direction of said creel board, and the axes of the bobbin holders of said second row being located laterally of the vertical planes respectively pass ing through the axes of the bobbin holders of said first row and intersecting the longitudinal axis of said creel board at a right angle.

2. A bobbin holder arrangement for spinning and preparing machines, which comprises in combination: a creel board, a plurality of first holding means substantially vertically suspended from said creel board and adapted pendulously and detachably to support bobbins, a plurality of second holding means substantially vertically suspended from said creel board and longer than said first holding means and also adapted pendulously and detachably to support bobbins, said first and said second holding means being arranged in a row extending in the longitudinal direction of said creel board with said first and said second holding means alternating with each other.
